To aZZ whom it may concern.'

Be it known that I, HERMAN J. STRUVE, a citizen of the United States,and a resident of Deshler, in the county of Thayer' and State ofNebraska, have invented a new and improved Broom, of which the followingis a full, clear, and exact description.

My invention relates more particularly to the comparatively long whiskbrooms employed in barbers shops and like places. Brooms of thecharacter referred to present very long brushing fibers usually of broomcorn and owing to the great length of the fibers they do not properlyreinforce one another, and the additional strain exerted on the bers,due to their length, results in the fibers breaking off at the rear end.Besides, the fibers do not offer the proper resistance for effectivebrushing.

ln order to oif'er-come the stated defects, I form the broom withbunched brushing fibers at the center, extending the full length of thebroom, and outside the central fibers I arrange separate layers ofbrushing fibers, the several layers being successively of de creasinglength from the front rearwardly. The bers of a particular layerterminate on approximately a definite line, presenting distinct zones ofdecreasing thickness from the front rearwardly. The several layers ofsuccessively shorter fibers have a springy action, somewhat analogous tothat of laminated springs of leaves of varying length, and thusreinforce the central fibers so that the latter will not break off atthe bridle or tie cords. As the longer fibers wear down, the differentlayers become available as brushing fibers, in addition to the centralfibers.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar' characters of reference indicatecorresponding parts in all the views.

Figure l is a side elevation of a whisk broom formed in accordance withmy inven-y and stiff, and terminate with substantially a blunt end at apoint below the core. @ver the filler fibers ll brushing fibers aresecured, and are designated generally by the numeral 13.' rThe relationof the brushing fibers to the filler 1l is such that a tapering space l2is defined by the filler and brushing fibers in. front of said filler,as clearly shown in Fig. 4, which1 contributes to allowing a springymovement to the fibers when the brush is in use. The brushing fiberscomprise a central or inner bunch of fibers designated by the numeralle, and extending toward the lower end ofthe broom are suc-` cessivelayers l5, 16, 17, of shorter fibers,

there being any desired number of such layers within practical bounds.As shown best in Fig. l, the fibers of a particular layer terminate onapproximately the same line extending around the broom, so that distinctzones are formed by the inner and outer brushing fibers, the zones beingobviously of increasing thickness from the front end of the broomrearwardly. rlhe broom is other-v wise finished in any approved manner,there being shown conventionally a handle 18 around which are severalseries of wires 19 for binding the ends of the fibers onto theprojecting end of the core. Below the handle the broom is provided withbridle members or tie cords 20, three of which are indicated in thepresent instance. rFhe tie cords serve :to secure the inner longerfibers le, as well as the fibers forming the successive layers, so thatAthe final point of flexure of all the fibers will be the same.

In use, the springy layers of fibers reinforce the longer fibers 14 andreinforce each other, so that the inner bunch of fibers will beprevented from breaking off at the tie cords, and successive layers offibers will have a similar effect on each other.

Having thus described my invention, f claim as new, and desire to secureby Letters Patent:

A broom, having a core, a filler of short fibers secured at their upperends to the core at the interior of the broom and terminating a shortdistance beyond the lower end of said core, and brushing fibers coveringsaid filler and meeting below7 the filler, the fibers and the fillerdefining an interior space of decreasing width below the core, thebrushhunched fibers extending to the lower end oi the broom7 andseparate springy 1ayers,' In testimony whereof' I have signed my thespringy layers being of deoreasinglength name to this specification inthe presence of from the innermost to the outermost layer, tWosubscribing Witnesses.
